The achromatic locus: effect of navigation direction in color space

T Chauhan, E Perales, K Xiao, E Hird… - Journal of …, 2014 - jov.arvojournals.org
An achromatic stimulus is defined as a patch of light that is devoid of any hue. This is usually
achieved by asking observers to adjust the stimulus such that it looks neither red nor green …

Hue linearity of color spaces for wide color gamut and high dynamic range media

B Zhao, MR Luo - JOSA A, 2020 - opg.optica.org
Hue linearity is an important property of uniform color spaces such that hues perceived to be
similar should be located on a straight line, an iso-hue line, in that space. Previously derived …

No difference in variability of unique hue selections and binary hue selections

JM Bosten, AJ Lawrance-Owen - JOSA A, 2014 - opg.optica.org
If unique hues have special status in phenomenological experience as perceptually pure, it
seems reasonable to assume that they are represented more precisely by the visual system …

Investigating unique hues at different chroma levels with a smaller hue angle step

W Bao, M Wei, K Xiao - JOSA A, 2020 - opg.optica.org
Unique hue plays a critical role in color appearance models and uniform color spaces. Past
studies investigating unique hues commonly used 40 Munsell samples with the same …

Simple color appearance model (sCAM) based on simple uniform color space (sUCS)

M Li, MR Luo - Optics Express, 2024 - opg.optica.org
A new color appearance model named sCAM has been developed, including a uniform
color space, sUCS. The model has a simple structure but provides comprehensive functions …
